This is what you might call a de-ssistive device – it takes two perfectly good hands to operate one rather feeble (although slightly sinister) one. I’ve got this version configured as two 4-DOF (degree of freedom) fingers and one 2-DOF thumb. You can actuate particular flexures in a finger by running the tendons through holes in the outside corners, and not activate other flexures by running the tendons through holes in the center. I’ve biased all three fingers backwards with tendons running along the back side, and that are then attached to rubber bands.

Every Thursday is #3dthursday here at Adafruit! The DIY 3D printing community has passion and dedication for making solid objects from digital models. Recently, we have noticed electronics projects integrated with 3D printed enclosures, brackets, and sculptures, so each Thursday we celebrate and highlight these bold pioneers!
Have you considered building a 3D project around an Arduino or other microcontroller? How about printing a bracket to mount your Raspberry Pi to the back of your HD monitor? And don’t forget the countless LED projects that are possible when you are modeling your projects in 3D!
